4-Methoxyphenylhydrazine hydrochloride （CAS # 19501-58-7) Amakuru
| Koresha | 4-mikorerexyphenylhydrazine hydrochloride ni intera hagati, ikoreshwa cyane cyane mu kubyara fenilhydrazine, kandi irashobora no gukoreshwa mu gukora ibindi bicuruzwa bivura imiti, nka 4-nitroindole na apixaban. Bikoreshwa kumarangi hamwe naba farumasi |
| Kwitegura | 4-mikorerexyphenylhydrazine hydrochloride irashobora gutegurwa kuva aniline binyuze muri diazotisation reaction. Fata aniline, aside hydrochloric na nitrite ya sodium, igipimo cya molar hagati yabo ni 1: 3.2: 1.0, banza ushyiremo aside hydrochloric, hanyuma ushyiremo nitrite ya amonium kuri 5 ℃, hanyuma ukore kuri 0 ~ 20 ℃ muminota 40 kugirango ubyare diazobenzene ya chlorine; Ukurikije igipimo cya molarine ya aniline na 1: 3.5: 2.5, hiyongereyeho ammonium sulfite na aside hydrochloric, kandi kugabanya, hydrolysis na acide bikorwa mu isafuriya yo kugabanya, igihe cyo kugabanya ni iminota 60 ~ 70, na hydrolysis na aside igihe ni iminota 50. Ubwa mbere, ammonium sulfite ifata aside irike ya hydrochlorike kugirango itange ammonium bisulfite, ammonium bisulfite, ammonium sulfite ikorana na diazobenzene ya chlorine ikora fenilhydrazine disulfonate, hanyuma ikagira aside hydrochloric ya hydrolysis hamwe na analyse ya aside. metoxyphenylhydrazine hydrochloride irateguwe. |
Andika ubutumwa bwawe hano hanyuma utwohereze
